Alpnca'tion fue@ February 9, 1914. serial Nb. Siamo.

To all whom z'timay concern:

Be it known that I, HENRYB. SAUERMAN, a citizen of the United States, residing at4 Chicago, in the "countyof Cookl and State of 5 Illinois, have invented a new and useful 1mof which the followingis a specification.

Myinvention relates to improvements in material-moving apparatus comprising, gen- 0 erally stated, an inclined cable-way supporting a traveling carriage thereon with a dumping-scraper or bucket connected' with the carriage, and a hauling-line through the medium of which `the movementsV of the carriage'and bucket are'controlled; and'my objects are to provide an improved form of apparatus of' this general character which will bel highly efficient in operation, be readily and positively operated, and whereby accidental dumping of the contents of the" bucket shall be avoided.

Referring to the accompanying drawings Figurel is a'viewin elevationof an apparatus constructed inV accordance with my 1nvention, the apparatus being' shown .in the position it assumes when dredging. Fig. 2 is a similar view of a part of the'mainand hauling cables and the carriage and bucket of Fig. 1,v this view showing the main-cable .taut and the bucket in the position Vit as'- sumes while being moved up on the maincable through the middle of the haulingcable, the carriage and bucket being shown in a'position closely adjacent to the point of dumping. Fig. 3 isa view like Fig. 2 showing the bucket in the act of dumping; and Fig. 4, an enlarged section taken at the line aon'Fig. 2, and viewed in the direction of the arrow. y l

The inclined main-cable whichwouldy be supported,VV in practic'e,to eXtendf` across' the ground to be' excavate'dor dredged, is represented at 5 and; is anchoredl atits lower end, as indicatedat, andpfat its opposite, upper, end connectswith a' tauting mechanism of any suitableand well known construction secured'to the upper endof amast 7, and, asshown,:Eormed'of'asystem of pulleys 8- connected with a 4cable 9 which passesV over a suitably operated drum "1 0, whereby the cable 9 may be' slackened or made taut at will.

bolts' 14'. vLocatedA betweeny thev plate'sjf12'f and` i Y 13 are pulleys 115 and 16 journaled on bolts.,`

17,- by which pulleys the carriage is `sup" Portedl on the ycable-way 5 and is-movable thereon. A-

`The' dumping'- scraper or bucket, represented at 18, and which issupportedfr'om the carriage 11,is"of'a'i'orm generally used, its'forward, open', ydigging-end "being provided with alcutting-edge portion 19.; 'The' bucket 18 is provided at opposite," sides nearW its closed, rear, end with 'lugs`20, one only. of which isl shown,with` which rVt'he'lower ends of' a yoke 21 are pivot'ed, as indicated` at 22', vthe upper fend of Vthe yoke 21 being pivotally connected withthe'l carriage 11,

as indicated at 2e; frhebueka is isjthus pivotally hungfromV thecarriage 'll'andzt al pointin the rear vof the centerl of gravity" 18a, with one of the branches '24 and 25l of" thedraft-cable which unite, as shown in Figi 'of thefbucket 'when'loaded The bucket`18', is connected at its front end, as indicated at;

2, a'slight distancebeyondthe bucket 18, tol

form a single" draft-cable as is oftenthe practicein constructions of Athis kind, the

draft-cable shown being formed with a section 26, in the orm of a head. The branch 25 'of-the draft-cable y'is-.preferably a chain which eXten'ds over 'a coil-chain sprocket wheel 27 j ournaled between the-plates 12 and '13V of the carriage 11 on a bolt" 28, and connects at oneend with a "bail'29jonfthe for'- ward end of the'bucket'l? in` advance of the center 'of gravity of th'e'latter.y Rigid withl the sprocket wheel' 27T` at opposite sides thereof, and located between the plates 12 and '13' andA reinforcing Aplates 30 secured to the ear-I riage and space'dtherefrom'by spacer bars 31, are'rat'ch'ets 32leach adapted' to copera'te with the' toothg33 on -a bell-crank lever 34; fulcrumed at its forward end, as'indica-ted at 35, to the carriage 11,v itbeing understood that one of thes'ejlevers-S Vis provided at.l

each side of Vthecarriage-[11, these 'levers being so: arranged that 'they normally hold the ratch'ets 32' against anti-clockwise rotation-'in Figs.i2 and 8, for the purpose here-y inafter explained. The'forward upwardlyprojecting ends of the'levers 34C are Vconnected'with a chai'nJSGwhich extends around a' pulley. 37 journaled on a'pin' 38 on' the head4 26 and` connects, as indicated zit/39, with a4 traveling block provided with a pulley 41 by whichthis block is supported on,and is movableA along the cable-way' l5, this blockvv Viio being provided forv coperation-with a stop 42 which may be set at any point on the cable-way 5 and which controls the point at which the bucket dumps, as hereinafter de.- scribed. rfhe carriage 11 and bucket 18 are adapted to be operated through the medium of the haulingeline, the section of which .be yond the block 26 is indicated at 43, this line passing over a pulley 44 0n the mast 7 and connecting with a drum 45 operated in any suitable manner. rI`he plates 12 and 13 are preferably held in properly spaced relation to each other by sleeves, forming spacers, on the bolts 17 and 28, as shown in Fig. 4, and on the bolts 14 in a similar manner. l l

In the operation of the apparatus, assuming it to be in scraping position (Fig. 1) wherein the cable 5 is slack and the bucket 18 lies on the material to be operated, the

bucket is dragged along the material bypulling on the hauling-line which causes the bucket to fill. f As soon as the bucket has filled, the operator, by operating the drum 10, draws the cable 5 taut, and by continued pull on the hauling-line hauls the bucket 18 and carriage 11 up the cable 5, the carriage,

bucket and the parts connected therewith as-V suming the positions as represented in F im 2, in which positions, it will be noted, the bucket 18 is held in a position to prevent its contents from dumping, the pawl members 84, by reason of their heavier rear ends, engaging with the sprockets 32 lwhich prevents the bucket 18 from prematurely swinging to dumping position should the haulinglinebecome slack during the operation of transferring the bucket from filling to dumping position. The stop 42 being in the ath of movement of the block 40, as soon as this block, by continued pull on the hauling-line 1, moves into engagement with the stop 42, its farther movement upward along the cable-way 5 is prevented with the result, upon continuing draft on the haulingv line, of causing the carriage 11 to move upwardly on the cable at about twice the speed of the movement of the hauling-line. As soon as the block 40 strikes the stop 42, the

levers 34 are rocked upwardly, thereby dis-y tion, by reason of the disengagement of the teeth 38 from the ratchets 32, as above stated, the bucket 18 is free to swing by gravity to dumping position, as represented in Fig. 3.

While I have illustrated and described a particular embodiment. of my invention, I do not wish to be 'understood as intending to limit it thereto, as the same may be variously modified and altered without departing from the spirit of my invention, it being my intention to claim my invention as broadly and completely as the prior state of the art will permit.
